PURPOSE:To effectively eliminate dust sticking to an optical head, to miniaturize the whole device and to improve reliability. CONSTITUTION:This device is provided with a cartridge 2 incorporating an optical disk, a loading mechanism 5 drawing the cartridge 2 into a position where a spindle motor 4 is loaded and a base plate 1 holding them. The loading mechanism 5 is provided with a guide holder 6 guiding the cartridge 2, a belt- shaped slider 7 moving together with the cartridge 2 and a shutter lever 8 whose other end part is loaded on the belt-shaped slider 7, a buffer mechanism 12 for cartridge with an air cylinder structure is loaded between the belt-shaped slider 7 and the base plate 1. An outdoor air passage 12a is provided on the buffer mechanism 12 for cartridge, and a nozzle 14 for suction and exhaust is loaded on the outdoor air passage 12a through an air tube line 15. The nozzle 14 for suction and exhaust is faced to the optical head 3, and the air is blown to the optical head 3 by the mechanism 12. |
